pip和Python在不同的路径

Question

I've been having some trouble installing Python packages and then I noticed that pip and Python were in different spots, which could be the problem. How do I align them back up?

Macintosh:~ Ryan$ which python
/Library/Frameworks/Python.framework/Versions/2.7/bin/python
Macintosh:~ Ryan$ which pip
/Library/Frameworks/Python.framework/Versions/3.5/bin/pip

And

Macintosh:~ Ryan$ python -V
Python 2.7.11
Macintosh:~ Ryan$ pip -V
pip 8.1.2 from /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages (python 3.5)

I'd like for everything to use 2.7 and hoping that fixing this will stop me from getting so many errors/notifications when I try to install certain packages like this:

Macintosh:~ Ryan$ pip install json
Collecting json
  Could not find a version that satisfies the requirement json (from versions: )
No matching distribution found for json

Answer 1

If you want to set up pip for 2.7, just download get-pip.py and run

sudo /Library/Frameworks/Python.framework/Versions/2.7/bin/python get-pip.py

and it will install pip and pip2 for you in the same bin directory as the python executable. You should still be able to install packages for Python 3 using pip3 or pip-3.5 .
